It would have to work really poorly to be worse than no civilization at all. And advising the gbaba "we are the humcylon, we reproduce via industrial mass production, we waste no resources on food or shelter or entertainment, and we have been hard at work converting entire planets that were not even attached to stars any more (this may have been observed in our world already) to battlefleets so, by the way, we have assigned a flotilla of star battleships to each gbaba, individually. No, you are the targets, not the commanders" might send a message.
Well, as previously stated - the Ark project wasn't the best, it was just the simplest avaliable.
And generally it seems that the project was a mess from the start; the fact that Langhore through some "politic manipulations" (what politic? The Federation was near extinction and they still waste time on politics?!) was able to come in charge of the project clearly demonstrated, that the Ark designers weren't the best in that job.
